的Netbeans 7.4：試圖刪除項目產生錯誤

Question

我試圖刪除揮杆基於應用程序的項目，使用「DefaultProjectOperations.performDefaultDeleteOperation」

，但我不斷收到此錯誤。

唯一的堆棧跟蹤我有如下一個，但現在我的無能什麼可能我是做錯了，或者即使這可能是一個NetBeans缺陷。

我使用NetBeans IDE 7.4。我無法升級到v.8.0，因爲使用這個IDE是一個客戶端規範。

任何幫助將不勝感激。

Answer 1

按照DefaultProjectOperations documentation，拋出異常，因爲ProjectOperations.isDeleteOperationSupported返回false。根據documentation for that method，由於項目沒有實現接口DeleteOperationImplementation，所以返回false。
據我所知，你需要實現該接口來刪除項目。
